* Add some tests to check the correct GET API endpoints are called
* Refactor adapters
1. Add integration tests for `urlFor...` and majority `handleResponse` methods
2. Refactor out `handleResponse` a little more into single/batch/boolean
methods
3. Move setting of the `Datacenter` property into the `handleResponse`
method, basically the same place that the uid is being set using the dc
parsed form the URL
4. Add some Errors for if you don't pass ids to certain `urlFor` methods
1. There are various things tests that can just have intentions added
into them, like filters and such like, add intentions to these
2. Start thinking about being able to negate steps easily, which will
lead on to a cleanup of the steps
